// all static variables into an own class, and to name this class
// Fl_Printer_Chooser or similar...
//
// Todo:
//
// - Currently preferences can't be saved, and there are options that
// are not yet used for printing.
// - This file can only be used as an include file in Fl_PS_Printer.cxx
// - The use of static variables should be avoided.
// - Probably much more ...
